About Sage 100 Contractor

Sage 100 Contractor, formerly Master Builder, is job-cost accounting and construction management software for small and midsize builders, remodelers, and specialty contractors. It's the long-running step up when generic accounting stops keeping pace with your jobs.

It's a desktop-era product sold through a large network of resellers, and Sage is pointing new customers toward Intacct Construction over the long run. That said, version 26.1 shipped for 2026, so it's still actively developed and supported.
